KNOCKDOWN PAPER BOX.

SPECIFICATION forming part of Letters Patent No. 474,610, dated May 10, 1892. Application filed November 23, 1891. Serial. No. 412,716. (No model.)

To a/ZZ whom t may concern,.-

Be it known that I, EBEN M. SCOTT, a citizen of the United States, residing at Shelton, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Knockdown Paper Boxes; and I do hereby declare the following to be a full, clear, and exact description of the inven-4 being so shaped that danger of tearing the material in light boxes is wholly done away with.

Vith these ends in View I have devised the simple and novel knockdown paper box of which the following description, in connection with the accompanying drawings, is a specification, numerals being' used to designate the several parts.

Figure l is a perspective of a box partially set up; Fig. 2, a plan view of the blank; and Fig. 3 is a plan View of another blank, illustrating a slight change in the details of arrangement.

It will of course be understood that my invention is applicable to all classes of boxes, whether the box or lids are made to telescope or whether the lids are more or less shallow. As the lids are made in precisely the same way that the `boxes themselves are made, I have not deemed it necessary to illustrate a lid in the drawings.

1 denotes the central portion constituting the bottom of the box or the top of a lid; 2, the side pieces, and 3 the end pieces. The side pieces are provided at each end with flaps 4, detached from the end pieces, each flap be- The end pieces are provided with iiaps 6, which are adapted to fold over flaps i and the corners of which (designated by 7 in the drawings) are adapted to enter slots 5, as clearly shown in Fig. 1.

In Fig. 3 I have shown slots 5 as placed lower down in flaps 4 when in the set-up position and farther toward the center. In order to correspond therewith, the engaging corners 7 of flaps 6 are placed farther inward, as clearly shown. 8 denotes the lines of folding between the side and end pieces and the bottom or top, as may be.

9 denotes the lines of folding between the side pieces and flaps 4, and l0 denotes the lines of folding between the end pieces and flaps 6.

The operation of setting up will be readily understood from the drawings. Flaps 4. are folded upward on lines 9. The side pieces are then folded upward on lines 8, the end pieces then folded upward outside of iiaps Li on lines S, fiaps 6 are folded over flaps 4: on lines l0, and corners 7 are passed into slots 5. The gist of the invention lies in the oblique slots used in connection with the corners of the flaps, all tongues being thereby dispensed with. After the corners of naps 6 have been placed in engagement with the slots outward strain upon the sides of the box or lid acts to place the lower edges of flaps 6 in contact with the lower ends of the slots. As there is no tendency toloosen flaps G, it follows that iiaps 4 must remain securely locked in position, so that the box or lid, as may be, will retain its set-up position against all the ordinary strains in use.

Many thousands of these boxes have been madeand sold, and I find no necessity whatever for using paste, clamps, or staples..

Having thus described my invention, I claim- A knockdown paper box formed from a blank consisting of a central portion, side pieces, and end pieces, said side pieces being provided at each end with iiaps et, detached from the end pieces, and each iiap being pro vided with an oblique slot 5, and said end pieces being provided with iiaps 6, which are adapted to fold over flaps 4 when assembled and the corners of which are adapted to enter the oblique slots.

In testimony whereof I afx mysignature in presence of two witnesses.
